To all 'Uf/1,0m 'it may Conifer/2.

.le it known that l.. 'l`i;vio'1l.xr Tatum. e. subject of the King' ot' Great Britain. and a resident oli Middlcshoro, British lColumliia, Canada, have made certain new an'l useful improvements in flutolnatio vllngine-Stops, of which the following ay specilieation.

illy. p1.'e.-;ent invention relates to autoinatio engine atopss, and my ohjeet is to provide a simpleand cll'eetive. arrangei'nent by which to ,shut oll' an engine supply valve in conneetion with rope drives, and 'tor actuation where ,the rope is broken and also where either a splice pulls out or the rope slacks to. such an extent as that it might jump .its

proper groove and eause Serious trouble,

With the ahove in mind my invention resides. in the features. of eonstiznction, ar rangement and operation to he now V(leaerilied iu connection with the accompanying drawinge, torniinzgr a part of this specil" nation, and .in whieh- .Figure .l is a side elevation. Fig'. ie an end elevation. lfigp is gr detail section taken on line 3--Ci"o'l" Fig. l, and, Fig. it is a similar view talien on line #it-'el oi. Fig., l'.

.Referring now to (heise ligures, 'kindieatcs the, usual grooved drum into the grooves ofwhich is wound the operating rope l5, the drinn beingactuated by an en- `ine el suitable character. have here ehown vthe operation engine in the' ordinary torni ot reciprocating Steam engine 'with a supply pipe C in which is disposed a cutoll' valve C in addition to the usual throtlle valve.

ln accordance with my invention olie end ot a valve eontrolling lever D is Szeeureil to a. Shaft (l above that portion ot' the operating engine l'artheat removed 'from the drinn A', this ehal't heing journaleil hori- Vonlally iny brackets d and havingv an arm ll extending :suhntantially parallel with the lever l) and connected to the cut-oli' valve ol tho engine before mentioned h v mean@- ot a .'erticallv lnovalile connecting rod lil which is preteral'lly.adjustable in length. Thus with the. lever l) raised and in its normal position, the, rotoli' valve of the engine is held open. Depending from points above opposite sides of the drum A are va hair oi tubular rod lf and lv, the RDPC? ends et which are pivotally mounted in ln'aelf no. f" respectively, so that they7 le directiono movement of il and the lnlnl foil valve to eloged po Serial No. 782,7!23.

the eahle l5 and the lower end l ol' which are provided with y\ct ,screwa` ,f"' wherehyv to :uljustahly Secure the legs of a Uaehaped har tl therein. its will he seen, the eroga piece ot' (he U,-.`1haped'l ar (i extends aero,- the l'aee ot' the drum A and may he adliunled *toward and away 'from the Ksaulev :es desired,

the tubular suhhorts lf and ll and the tlshaped har G' forming` a. pivoted tilting: frame whieh may he swungl in either divrection whenever the operating` rope l parte or slaclie lo a suliieient degree.. Depending along' side of the tubular rod l1" is a har li, the upper end of which is pivoted in the hraeh'et f a5 Shown in Figi". 2, and the lower end of which in connected with said rod l? hy means` ot a Stud /i` onwhieh in journaled a roller h. A

."is particolari),`- shown in Fig. l, the lever l) is provided zuljaeent its outer tree end with a depending extension E' which in the normal poeil'ion ol the parte rests upon the roller fr', the said tree end of the lever l2* extending,y hetween the upper end of the bar r support F as partiinin lai-l)Y shown in f Q. Thus il. lee-seen that should the operati-inFIA rope l part eit .ier hy pulling' out a Splice or lofi7 breaking tween Spliees the hrolien strands will neceesarily strike the tilting frame and move the same over to one side or the other. lt will he further Seen that any' such movement of the tilting frame will result in moving' the roller 7l. from beneath the'lever exn tensionv i3' and that as a result the said lever: will swing downwardly and lower the entf 'fion7 these n oveinente beingl apparent hy refer-c te to a i comparison of the full and dotted positions shown in ifiir. l.

ly virtue of the fact that the i-ishapr-al'y har (l i5 ailiuetahle in its tubular supports l" and FQit will he seen that the tilt-ing l'ranie may he adjusted to a selected poellion. with respect to the vdrum A in order that the .stopping mechanism may he regte lated to operate if there is sullicieut slaek in the operating rope to cause the same to liump a groove of theflrum.

lt will he seen tha-tiny'Y improved meeha-. nisin is simple., may' he readily inetalled in Connection with rope drives now'in use and will loe durable and eleetive in operation.

l claim:

l. The comin/nation with :L drive rope drinn and its power mechanism, the latter being provided with .a moet?, of a trip lever pivoted at one end and having connection with the ent-ofi' and provided With a de'- pending extension at its opposite end, and a U-shaped frame pivotally supported with its lower Cross bar transversely above and in close proximity to the rope drum to swing in the direction of movement of the rope, said Ytrame consisting of depending tubular rods and a U e, raped bar having its legs adjustably secured in the lower ends of the said supports, and a roller carried by the ii'rame and normally supporting the depend; ing extension et' the trip lever, all for the purpose described. l

The combination with a drive rope drinn and its pov-fer mechanism, the latter or which is provided 'ith a. eut-off, of a trip lever pivoted at one end above the power mechanism and having connection adjacent its pivoted end rwith the cut-oil', and a iframe pivotally supported transversely above the drive rope drum and pro vided with a cross bar adjacent to said drum and adjustable toward and away from the same said frame normally forming a direct support for the free end of the trip lever and being movable in the direction of movement of the rope, all for the purpose dcscribed.

3. The combination with a drive rope drum and its power mechanism, the latter of which is provided with a eut-oil', of a swinging frame movable in the direction of movement of the rope and having` a cross bar adjacent to and transversely above the drum, a trip lever pivoted at one end above the power mechanism and having its free end normally disposed directly on and snpported by the said swinging frame, and an operative connection between the said trip lever and the cut-oft' of the power mechanism, all for the purpose described.
